To all whom 'it may concem: i

Be it known that I, ROBERT T. BAIGLY, a citizen of the United States, residing in the city of New York, County of New York, and

"State of New York., have invented a new and useful Improvement in Rubber-Soled Shoes, of which the following is a specification.

The object of the invention is to provide a rubbe' sole or heel for a Shoe which will ive the greatest amount of elasticity and a ord a greater resistance to slip ing than has heretofore been obtained. %lus I do by means of air cushions, having air vents either on the heel or on the soleor at both places.

In serve to illustrate my invention, and in which similar letters represent corresponding parts, Figure 1. represents the entire ground side of my improved rubber sole; Fig. 2. represents the ground side-of the sole or forward part; Fig. 3. the ground'side of the' heel; Fig. 4. the up er side of the heel; Fig. 5: is a cross-section& view of the heel.

A represents a rubbcr or flxible sole; B air chambers and C air inlets.

When it is desired to use the sole on a flat shoe such as a boating, tennis or other form of'outin shoe, the form shown in Fig. 1 is referab y used, showing the flat rubber surace and the two air chambers. When, howthe accompanying drawings which ever,'the a plicaton is to be made to an or dinary wallng Shoe, it will be suflicient to attach the parts shown in Eigs. 2. and 3. to such shoe. i

An additional advantage of my invention lies in the fact that the form of air chamber shown with its air inlets gives a greater suction power than in any other form of rubber sole which has been known or used.

What I claim as my inventon is:

1. The combination With a Shoe, of a'rubber sole or heeltherefor provided with airchambers' projecting below the tread surface thereof, and air inlets leading to said chambers, as set forthc 2. A non-slipping device for the sole or heel of a shoe, eomprising an elastic airchamber projecting below the tread surface thereof and inclosing an open space on such tread surface, and air inlets leading. to said chamber whereby said chamber is caused to exert a suction action as the air is 'sucked therein and exhausted therefrom and thereby prevent sl'pping, as set forth. i

In witness whereof, I have hereunto set my hand this 19th. day of March,`1907.

ROBERT T. BADGLEY.
